"Be careful while driving if..."
Traffic & Driving Tip by nudibranch

Be careful while driving if you come across a traffic light that's flashing yellow in one direction and flashing red in the other. In parts of America where people know how to drive, those who see the flashing red will treat it as a stop sign, while those seeing flashing yellow can proceed with caution. No one in this town seems to understand this, so it's best to treat it as a four-way stop. Otherwise, someone may pull out on you.
